> Do we have to? Its a problem if we want Master to host regions and its just a problem anyways. See HBASE-19828 for scenarios mostly around cluster shutdown where the order in which processes go down is hard to control and it happens that a server-hosted-client is trying to rpc a missing hbase:meta. Eventually, we'll time out (server-hosted-clients have their retries upped) but bad for MTTR and unit tests.
